by Sam Blowsnake
(310) In those days he (Thunder Cloud) was a poisoner, and he used to travel in the night, they say. That sort of thing he was going do. At night, around 11 o'clock, it was, he got ready. A group of people by the name "B[lowsnake]," these he was going to poison there, he said. We laid there listening. We were lying in the lodge and then outside he made some noise. Because we thought he was a poisoner, we were afraid of him. That he himself was in control of our household is what he said. They couldn't accomplish anything, Because we knew him to be a poisoner, we were afraid of him. He came from among the various spirits, a reincarnated man, someone who, as long as we did not displease him, would not do anything to us. So we did whatever he said. That's the way it was.
(311) He had been married to my oldest sister, but he would marry again the second oldest, he said. Where she had been, there where Earthmaker dwells, his wife was living there. He said that my sister, the second wife who was above, resembled her. "I think that she must be what I left behind when I came," he thought. He went up above to where Earthmaker resides to see his wife. He noticed that she was still there. "I saw you there among the humans. How can it be? I thought, since I caught of glimpse of you when I came back," he said. "Where was I to go? You left me here when you went away, and I have remained up to the present time," she said. The woman said, "What person do you mean? Bring her here to me," she said. Thus it was she he meant, my sister, the second one that resembled his wife up above; and for that reason he wished to marry her, he said. He was both a holy man and a poisoner, so they let him marry her. It was because they were afraid that if he they didn't permit him, he would poison them. They let him marry her because he was a holy man. Thus, he married two women, he used to say.
Up above where Earthmaker lives, where I came from, here Earthmaker said to me that I was to bring back four men, he said, and I was to look for men of virtue. (312) He did not mean the quick tempered sort or those of changeable ideas, but really virtuous one, that kind I would take back. Thus, he was to go back to Earthmaker taking four of them, he used to say. 
Commentary. "poisoner" — this term is conventionally used for a witch.
"his wife was living there" — she is a spirit being. When she was reincarnated on earth, she was Sam Blowsnake's (deceased) eldest sister. His subsequent remark shows that Thunder Cloud was married to her when he himself was in Spiritland. Both of them were true spirits (waxopini) and not ghosts.
"resembled her" — Radin says, "It was frequently believed that the resemblance of some living person, especially of some young person, to an older person who has died, meant that the younger one was the reincarnation of the older one. For this reason, in adopting a child to replace one that had died, parents always tried to find someone who closely resembled the deceased." 
"when I came" (húną) — J. O. Dorsey recorded that húną means, "to be coming hither, to this place, not his home."  Thunder Cloud puts it this way because, as a spirit (waxopini), his true, original home is in the heavens, and coming here to earth is therefore a place other than his home.
